espandere ((x-1)^2)/2

Soluzione

espandere

\frac{( x - 1 ) ^{2}}{2}

\frac{x ^{2}}{2} - x + \frac{1}{2}

Fasi della soluzione

\frac{( x - 1 ) ^{2}}{2}

(x - 1)^{2} = x^{2} - 2 x + 1

= \frac{x ^{2} - 2 x + 1}{2}

Applica la regola delle frazioni:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{x ^{2} - 2 x + 1}{2} = \frac{x ^{2}}{2} - \frac{2 x}{2} + \frac{1}{2}

= \frac{x ^{2}}{2} - \frac{2 x}{2} + \frac{1}{2}

Dividi i numeri:

\frac{2}{2} = 1

= \frac{x ^{2}}{2} - x + \frac{1}{2}

(3 z - \frac{2}{z})^{7}

\frac{1}{( 1 + 2 x ) ^{4}}

\frac{( x + 1 ) ^{3}}{x ^{2}}

(sin (x) cos (x) + 1)^{2}

(sin (\frac{1}{x}) + cos (\frac{1}{x}))^{2}
